To all whom it 'ntay concern.-

Be it known that I, FRANK P WILHELM, a citizen of the United States, residing at lo tosi, in the county of Grant, State of Wisconsin, have invented certain new and useful Improvements'in Seeding Attachments for Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in seeding attachments for plows; and the object in general thereof is to construct a device of that nature which may be attached to a plow of any desired description and which shall comprise a main frame with which the plow is connected and carrying a feed-hopper, the bottom of which is of trough shape and contains a duplex screw convcyer.

The invention also includes the use of a pair of floating gears for transmitting motion from the trziction-wheel of the main frame to the screw-conveyor.

Further in'iprovements consist in the attachment to the main frame of a disk-shaft carrying a series of cgveringalisks; and still further improvements include the means for adjusting the disk-shaft to any desired angle and for regulating the feed mechanism in the ho per.

ith these and other objects in view the invention consists in the particular construction, combination, and arrangement of parts, all as hereinafter fully described, pointed out in the claims, and illustrated in the accompanying drawings, forming a part of this specification, and in which' Figure l is a side elevation of a combined plow and seeder constructed in accordance with this invention. Fig. -2 is a top plan view of the same. if 3 is a longitudinal vertical section on the line 3 3 of Fig. 1. Fig. 4 is a detail View in elevation-of the floating gears, showing the same connected with the gears on the wheel and the feed-conveyor shaft. Fig. 5 is a detail View in elevation showing the means for regulating the from the hopper.

Similar parts are designated by the same reference-numerals in the several views.

Referrin to the drawings the main frame of the mac line is shown as comprising the side beams 7 and 8 and the cross-beani 9, connecting the side beams and extending be- 8, as shown, and provided at. itsoiher en'd ence to the cross-beam .desired.

feed sion 28, bent upwardly and around the rear yond beam8 for the attachment of the rear end of a plow-beanrlO, carrying a pair of shovels 11 of any preferred description,

The frame is supported on one side by a traction-wheel 12, journaled in'bearings in beam 7, and on 'the other by. the rearvend of I the plow-beam, the front end of which is connected to a guide-beam 13, as sliown,"attached to the front end of beam 7. The rear portion of said guide-beam is bifurcated and provided with a series of alining perforations,

there being aleveler 14, having one end pit otally connected with the front end of beam with perforated upwardlextensiam 15, 10 ing through the bifurcated portion oi E-r'l-ij. guide-beam and adj u'stably retained in place therein by a bolt passing through the perforations in said guide-beam and extension, whereby the angle of the leveler with refer- Mounted upon thempper portion of the frame is a feed-hopper 16, provided with aidividing-platc 17, as shown, and with a removable cover. isattachcd a pair of curved plates .18, spaced apart and forming a trough, in which the screw conveyor 19 works,,each plate having a spout 20 connected therewith, through which the seeds are scattered. Thescrew conveyor is provided with right and left hand blades. Workingin the lower portion of said hopper is a curved plate 23, embracing the upper portion of the-conveyer and provided with a pair of loiigitudinally-extending feed-open ngs 24, located on respective sides of the \I'shaped division-plate 17 in eloseproxiniity thereto. The outer end of said plate has connected thereto a screw 25, provided with a handwheel 26, through which said screw passes. To permit alougitudinal movement of said scrcwand. retain the hand-wheel in place, there is attached to the adjacent hopper end a bracket 27, embracing said wheel on both. sides thereof and provided with alining openings to permit the passage of said screw therethrough. Plate 23 is provided with an extenside of the hopper to form a pointer, said side being calibrated, as at 29. It will thu'sbe seen that by. moving the hand-wheel in one direction or the other a correspondinglongn tudinal movement of plate will result and that the feed from said hopper may he in this may be varied, as Q To the underface of said hopper way exactlyre latedfithe pointer-.indioat' s the correspon ing figures on the calibrate hopper side; y

v The traction-wheel carried by the side beam 7 is provided on itshub witha-gear 30, while the corresponding end of the screw conveyeris provided'with a gear 31. Pivoted to the outer side of beam 7-is a metal rod 32, carrying a stub-shaft-33, on which are located a pair of floating gears 34 and 35, adapted to mesh, res ectively, with gears and 3 Ion the wheel-hu and conveyor. To the on ter end of rod 32 is connected a link 36, pivoted at its opposite end to a 1evcr'37. -It=will be therefore apparent that by movin lever 37 down:

wardly the floating gears will be moved into mesh with thewheel-huband conveyer-gears and -that motion will thus be transmitted from said-wheel to operate the conveyer. A

movement of lever 37 in the opposite direction will in flike manner release the floating gears from engagement with the hub-gear and conveyer-gear, and rotation of the conveyor will therefore cease.

Bolted to the-rear end of beam Tis a pair-of braces 38, the oppositeonds of which'are attached to the upper portion of a disk frame 39, as-shown. -Mounted in the extensions-4O of said frame is a disk-shaft 41, carrying a plurality ofcircular disks 42. .The diagonal brace 43 connects the main braces 38 --with T beam 8, as shown,-whil'e one of the extensions 40is connected, by means of an-eyebolt 44, with the main-braces 38, as shown.

. The angle of the covering-disks may be ad justed means of a lever 45,- journaled in the bra'c 'et 46 at the rear end of beam 8 and having itszlower end connected, by means of alink-47, with the corresponding-extension of the disk-frame. a

The movement of the lever in one direction or the other will accordin ly-result ina corresponding movement of t edisk-frame by means of the link connection between the two, and the angular position of said diskframe may therefore be exactly adjusted. The disk-frame is retained-in 'its ad'usted'po sition by means of a spring-presse carried on the lower end-of-a supp emental lever attached to the lever 45' and adapted to lock with the teeth of a ratchet 49-,fastened uponthe-pivot 50, upon which lever 45 is pivoted.

Owing to the provision of the curved plate, which embraces-the upper portion of'the scre'w conveyer and has its openin s approaehin thesides of-the divisionl ate, it will-be o vious that the feed from the hopper may be completely regulated-as desired, as the o' erative extent of the feed-openings in said ate may be adjusted at will by movingsaid late in one direction or the other. It will liliewise be apparent that the partitions .of the hopper may contain difl'erent kinds of grain.

..- wem a? pen is shown {is-having a single division-plate,

'.andz .the= plowebeam as provided in' consefiuence with but two shovels, it will beready-understood that two-or three divisiontes may be made use of, in which case the curved plate will be provided accordingly with three or 'four feed-openings, there being a corresponding number of spout-plates carriedby the hopper and of shovels secured to the beam.

Owing to the rovision'of-a leveler at, the forward end of t e frame .theground-will be smoothed or planed to-acertain extent-arid Obvious modifications an changes may-be made within the scope of the claims without departing from the-spirit of 'the invention,.

the elods, s tones, &c., will be throym toward 8o \VhiCll-lSilOl'riDtCIldGd to be-limited to the-exact description shown and described.
